Stator of alternator having lead wires firmly held on circular coil end of stator winding

摘要

An alternator includes a stator and a rotor disposed inside the stator and rotated by an engine of an automobile. The stator is composed of a cylindrical stator core and a stator winding held in the stator core. The stator winding extends from an axial end of the stator core, forming a circular coil end along an axial circumference of the stator core. Lead wires led out from phase-windings in the stator winding are held on and along the circular coil end and bonded thereto with adhesive. A depressed ditch is formed on the coil end, and the lead wires are disposed in the depressed ditch and firmly held therein to prevent movement of the lead wires relative to the coil end.
